No - we're not interested in the internal data structure.
What it relevant here is the size of the PDU that's
put out over the wire.

Try running the application with the '-d' option,
to dump the raw incoming/outgoing packets.
*That* is the dump that I was talking about.

The variable 'pdu' is a pointer.
So yes - the size of it is almost certainly going to be 4.
(assuming a 32-bit O/S). That's not useful information.


What does the traffic on the wire look like.

Also - how are you setting up the administrative
settings for this request? (Community string,
or SNMPv3 user)

It also looks as if you are sending a GET request with
an empty varbind list. I.e. you are asking for nothing?
